WASTE-PIPE STOPPER.

Application filed April 24, 1915.

To all whom t may concern Be it known that l, EDWIN Gr. ADAMS, a citizen ofthe United States. residing at Medford, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Vaste-Pipe Stoppers, of which the following is a speciication. y

An object of the invention is to provide a stopper for use on waste pipes and the like, such as are generally employed in connection with wash basins, bath tubs and other similar structures.

The invention contemplates, among other features, the provision of a stopper that can be readily moved into a closed position with respect to the waste pipe so that the contents of the basin or the water flowing into the basin cannot flow outwardly through the drain or waste pipe thereof, 'whereas the stopper can also be readily moved into an open position to kpermit the basin to be drained, the stopper being so arranged that it cannot be readily lost as is ofttimes the case with the usual chain-supported stopper, and operated so that it is not necessary for the operator to immerse his hand in the contents of the basin.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specilication, in which similar characters of reference denote corresponding parts in all the views, and in which: i Y

Figure 1 is a side elevation of the stopper, showing the same applied to a basin, with the basin and drain shown in section, the stopper being in open position; Fig. 2 is a front elevation of the structure shown in Fig. 1, the stopper being in closed position; Fig. 3 is a plan View; and Fig. 4 is a horizontal sectional view taken on the line 4 4 in Fig. 1.

Referring more particularly to the views, l disclose a basin or tub structure 10 which in this instance is provided with a ledge 11 having the usual overflow opening 12, said basin including a drain or waste pipe 13 which communicates with the bottom` of the basin, the upper edge of the pipe forming a seat 14. A plate 15 is suitably secured to the ledge 11 and projects forwardly from the rear wall of the basin in order that a rod or stem 16 can slide through the plate, the lower end of said rod being preferably bent at right angles and curved downwardly Specification of Letters Patent.

to connect with the upper end of a stopper body 17 which consists, more particularly, of a rubber-like disk 18, a cap 19 and a tubular extension 20, the lower end of the rod 16 being connected with the capfl) and the disk 18 being interposed between the cap and the extension. The extension also has the lower end of the rod 16 extending into the same in order to secure the disk rigidly between the cap and the extension, said rod also passing through the disk, and the extension is provided with openings 21, the lower end of said extension having a series of slots 22 through which pass the usual wires 23 arranged in the drain pipe to prevent solid bodies or substances from passing into the drain pipe and clogging the same.

Now it will be clearly seen that the stopper body operates in the upper end of the waste pipe and when in closed position will have the disk 18 reposing upon the seat 14, thus closing the waste pipe, the stopper body being guided in its vertical movement by the lower end of the extension sliding with respect to the cross wires or mesh# like construction which prevents solid bodies from passing into the wastepipe so that the lower end of the extension forms a guide for the stopper body. A. stop member 24 is adjustably supported on the rod 16 and the upper end of the rod terminates in a knob 25, an eXpansible helical spring 26 being arranged to encircle the upper end of the rod, with one end bearing against the knob and the other end bearing against the plate 15, thus normally holding the stopper body in open position with respect to the waste pipe. Mounted to swing upon the plate 15 is a lever 27 having its lower end provided with lateral projections 28 adapted to bear against the upper face of the stop member 24, a spring 29 on the plate 15, bearing against the upper portion of the lever 27 to hold the projection in line with a portion of the stop member 24.

Now assuming that the stopper body is in the position shown in Fig. 1 so that the contents of the basin can 'liow through the openings 21 and thence into the drain pipe, when it is desired to move the stopper body into closed position with respect to the drain pipe it is only necessary to press downwardly on the knob 25, thus moving the rod 16 against the action of the spring 26 until the disk 18 reposes upon the seat 14. 1t will be seenthat a downward movement of the4 rod causes the stop member 24 toV move" in the drain pipe, will be prevented from,

passing` into said drain pipe. By exerting a pressure" against the upper end of the lever 27 the said lever will be operated against the action of the spring 29 to remove the projection 28 from engagement with the stop member, thus permitting the spring 2G to act Vand move the rod 16 upwardly to remove the stopper body from closed position, the stop member 24 being adapted to engage the under side of the plate l5 when the rod 16 moves upwardly to limit the upward movement of the rod and prevent the extension of the stopper body from being removed from slidingY engagement Vwith the cross wires 23 in the drain pipe.

From the foregoing descriptionit'will be seen that the construction described consists of few and simple parts, can be readily operated and is pa 1ticularly useful in that in` the operation of the device it is not necessary for the operator to immerse his hand into the contents of the basin.' Furthermore, by having the stopper body arranged and secured as mentioned the stopper body cannot readily become lost as is ofttimes the case with the ordinary rubber Stoppers which are generally employed to close the drain pipe and which, usually supported by a chain, frequently break away from the `on the lower end of the rod and movable into open or closed positions with respect to the drain pipe when the rod is actuated, means for guiding the stopper body into and out of closed relation to the drain pipe, a spring for said rod and normally holding the same in its uppermost position to snpport the stopper body in open position, .a stop member on the rod, and means on the plate and adapted to engage the stop meniber to hold the rod against upward movement and secure the stopper body in closed relation to the drain pipe.

A stopper for the drain pipe of a basin comprising a vertically movable rod, a stopper body on the lower end of the rod and movable into and out of closed relation with the drain pipe, a spring for the rod to normally move the rod upwardly and secure the stopper body in open relation to the drain pipe, a lever, and a stop member on the rod and adapted to be engaged by the lever to hold the stopper body in closed relation to the drain pipe, `said stop member limiting the upward movement of said rod.

n testimony whereof I ai'lix my signature in presence of two witnesses.
